以下のようなcsvから6つの配列(各列に1つ)を作成したい:

最初の列はポイント名 (Pt_name) で、文字列が含まれています。他のすべてには浮動小数点数が含まれています (Hz_angle、Vz_angle、Slope_Dist、Reference_Ht、Instrument_Height)

目的は、float 列の要素間で数学演算を実行できるようにすることです。

何か案は？

それをテストしませんでしたが、次のようなものが動作するはずです:

import csv

Pt_names = []
Hz_angles = []
Vz_angles = []
Slope_Dists = []
Reference_Hts = []
Instrument_Heights = []
with open(csv_file, 'r') as fh:
    reader = csv.reader(fh)
    for row in reader:
        Pt_name = row[0]
        # list comprehension for float conversion
        Hz_angle, Vz_angle, Slope_Dist, Reference_Ht, Instrument_Height = [float(value) for value in row[1:]]
        Pt_names.append(Pt_name)
        Hz_angles.append(Hz_angle)
        Vz_angles.append(Vz_angle)
        Slope_Dists.append(Slope_Dist)
        Reference_Hts.append(Reference_Ht)
        Instrument_Heights.append(Instrument_Height)
